Stack Infrastructure has secured $3.3 billion in green financing for data center development.

The IPI-owned company announced it has cumulatively fundraised the money to support its global presence.

The company has not said what the loans are secured against.

Stack broke ground on its Silicon Valley expansion last month and plans to allocate $1.4bn to the site to develop water and energy-efficient digital infrastructure.

An additional $750 million has been directed towards cooling solutions, green infrastructure, and recycled steel in Loudon County, Virginia.

Stack campuses in Milan, Italy, will receive $1.2bn to support water-efficient infrastructure, electric vehicle charging stations, e-waste recycling programs, and public garden area redevelopment, including domestic beehive colony settlements.

“Our top priority is to assist our clients in meeting their sustainability targets with the speed, scale, and certainty required to deliver efficient, AI-ready capacity,” said Brian Cox, CEO of Stack Americas.

John Eland, CEO of Stack EMEA, added: “Our dedication to sustainable practices and obtaining green financing empowers Stack to expedite and fulfill our ESG initiatives.”

DCD reported last month that Stack had received $240m in green securitized notes and had accumulatively raised $2.83bn in notes. 2023 saw Stack issue $290 million in securitized notes in November, $250m in August, and $250m in March.

Stack’s data center portfolio includes 4GW built or under development and an additional 2.5GW of planned and potential expansion. The company has sites across 24 markets, including Stockholm, Sweden; Zurich, Switzerland; Osaka, Japan; Canberra, Australia; and Seoul, South Korea.
